3 Claims.

My invention relates toa suction nozzle for vacuum cleaners or the like,and more particu- Germany August 15, 1936 larly to a nozzle which ismovable in two diiery ent planes to permit-it to follow the surfacebeing cleaned.

An object of my invention is to provide an improved suction nozzle whichreadily assumes the desired position, depending upon the shape of thesurface being cleaned.

Another object of my invention is to provide a nozzle with a ball andsocket connection to a conduit, which permits the lnozzle to rotate inthe plane of the working surface and permits tilting of the conduit withrespect to the nozzle and working surface.

Another object of my invention is to provide an improved ball and socketconnection for a suction nozzle of rugged construction, consisting of aminimum number of parts, which may be readily assembled together andmanufactured at a. relatively low cost.

What I consider to be novel in my invention may be better understood bya reference to the following specification and appended claims whenconsidered in connection with the accompanying drawing, in which Figure1 is a plane view of my improved nozzle located in position for cleaninga window; Figure l2 is a sectional view, on an enlarged scale, of thenozzle and connector; Figure 3 is a sectional view, taken on line 3-3 ofFigure 2,; Figure 4 is a bottom view of the nozzle; Figure 5 is a topView of the nozzle; and Figure 6 is a perspective view'of a modifiedform of pivot.l

Referring to the drawing, I0 indicates my improved nozzle connected by aconnector II to a suction conduit or tubular handle I2. Nozzle I0 isshown located in position on a window .it for cleaning surfaces havingsharp corners,

such as windows and the like.

Il of connector II. The two balls Il act as' pivots for the connector II, permitting the nozzle I2 to be inclined at a greater or lesser angleto the working surface as desired without permitting relatively looseuniversal movement of the handle. To permit the nozzle Ill to rotateabout the connector II so that it may follow the irregular boundary ofthe surface on which it is working, a recess or track I8 is provided nthe two parts I5 and I6 oi' nozzle Ill in a plane.

parallel to the iiat surface of thenozzle in which the balls Il areadapted toride. The connector II is provided with a passage I9, whichcommunicates with an opening'23 in the nozzle I0 at one end, and withthe hollow tubular conduit I2 at the other end. As may be better seenby.

reference to Figure 3, the provision of. the balls Il for pivotallysecuring connector II to the nozzle and the track I8 cooperate toproduce the desired movement of the handle I2 and rotary movement of thenozzle I0, without in anyl way obstructing the passage between thenozzle I0 and `conduit I2. Also, the assembly of the nozzle andconnector simply requires that the connector be inserted in one of thetwo .l

parts of the nozzle, the -two pivot pins or balls I'I located inposition, and then the other part of the nozzle passed over theconnector andA secured by means oi' the screws 20 to the firstmentionedpart of the nozzle. This produces va relatively simple constructionforaccomplishing the desired purposes which maybe very r y i assembledtogether. The bottom of part I6 is a To permit ready rotation of thenozzle I0 and at the same time to permit the tilting of the conduit orhandle I2, connector II is provided with a balll ljoint adapted to t ina spherical cavity or socket provided in the'two parts I5 andiIG ofnozzle I0. The two parts I5 and I6 are secured to the ball Il ofconnector II by substantially flat surface of triangular shape. aroundthe edges of which is secured an annular brush 2|. To insure the passageof the air into the nozzle adjacent thel free end of the brush 2i, aprotective band 22 is secured around the edge of the nozzle I0 and isclamped in position between the two parts I5 and I8. In some cases,

it may be found ydesirable to locatethe band 22 on the inside of thebrush 2I` instead! of the outside, as shown in the drawing. As betterindicated in Figure 4, opening 23 of nozzle III is located substantiallyin the center of the nozzle, and communicates withthe ypassage I9 oi'connector II. lInstead of the balls II for pivoting the connector II, acylindrical pin 2l, as shown in Figure 6, may be used and connected toan arcuate segment 25, which is adapted to ride pin 2l may be arrangedto ride directly in the track Il o! nozzle I 0 without the provision ofthe segment 2l.

From the foregoing,'it may be seen that an improved nozzle is providedwith a connector which permits the nozzle to rotate, to permit it totravel around an irregular surface, and also permits the conduitconnected to it to be inclined at any angle desired by the provision ofa ball and socket joint with pivot means for limiting the movement ofthe joint in some respects, without at the same time interfering at allwith the operation of the nozzle. In addition, the

' nozzle and' connector are provided' with a minif mum number of simpleparts that may be readily a connector for connecting said nozzle to saidconduit and having a ballon one end seated in the cavity in said nozzle,two pins carried at opposite sides of said ball, and arcuate segmentsconnected .to said pins and adapted to ride in an annular track in saidtwo part nozzle parallel to the face of the nozzle whereby the nozzlemay rotate in a plane parallel to its face and the conduit may move ina. plane perpendicular thereto.

3. In a vacuum cleaner including a nozzle adapted to engage a relativelyflat working surface and a conduit, a ball and socket pipe jointconnecting saidnozzle and conduit, meansproviding for limi-ted tiltingand rotary movement between said nozzle and conduit comprisingcooperating pivot and track means disposed respectively one on the balland one on the socket with portions located in diametrically oppositepositions relative to the ball and riding in said track providing forunobstructed passage through said pipe joint.
